How is the validity of the e-way bill calculated?

The validity period of the e-Way bill is calculated based on the ‘approximate distance’ entered while generating the e-Way bill. For every 100 kilometers, a validity period of one day is calculated. The same will get expired on the midnight of the same day. For example, if I have generated e-way bill on 04-04-2018 at 10 AM, then the same will get expired on 04-04-2018 at 11.59 PM.

The validity period of the EWB is calculated based on the ‘approx. distance’ entered while generating the EWB. For every 100kms one day is a validity period for EWB as per rule and for part of 100 KM one more day is added. For ex. If approx. distance is 310KMs then validity period is 3 plus 1 days.
